Based on the interpretation we read in <R72.D>, the wording states "additional air cylinders or rotary actuators may be used". This does not specify name brand such as "Bimba" as years past.
May we use other brand air cylinders such as PHD Air Cylinders or SMC Air Cylinders so long as they meet <R72.D> "size up to a maximum of 24-inch stroke and 2-inch diameter."?
